[PATCH 4.19 22/33] wifi: cfg80211: fix sband iftype data lookup for AP_VLAN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Felix Fietkau <nbd@xxxxxxxx>

commit 5fb9a9fb71a33be61d7d8e8ba4597bfb18d604d0 upstream.

AP_VLAN interfaces are virtual, so doesn't really exist as a type for
capabilities. When passed in as a type, AP is the one that's really intended.
